Marine and Coastal Access Bill [Lords]

I am pleased to follow the hon. Member for North Essex (Mr. Jenkin) and I agree with, I think, every word that he said. A hundred years ago in 1909, most of the British fishing fleet had no engines. The boats were sailboats, and virtually all of them were made of wood. Not one had sonar to identify where shoals of fish were. Today, our fishermen have a fleet of modern, steel-enclosed, sonar-equipped, satellite-guided vessels. They have weighted and gated trawl nets that extend for 2.5 km, yet the astonishing fact is that the British fishermen of 100 years ago caught 13 times more fish than we do today. For all our modern technology, we can do little more than vacuum up ever smaller fish in ever smaller numbers. We are fishing down the food chain. Almost exactly two months ago, the European Commission put out its green paper on the common fisheries policy. Among its findings, we learn that 88 per cent. of the EU's stocks are overfished and that 93 per cent. of North sea cod are caught before they can breed. Globally the position is little better, with 80 per cent. of marine stocks either fully exploited or over-exploited. A paper published in Nature six years ago, in 2003, concluded with the stark assessment that the global oceans had lost more than 90 per cent. of large predatory fish. However, if the average length of the fish caught off the west coast of Newfoundland fell by 1 metre between 1957 and 2000—and it did—we must not imagine that we are dealing with a collapse simply of fish and fish stocks. Rather, we are dealing with a collapse of whole eco-systems. Both target species and a huge biomass of by-catch species have been removed from continental shelf seas. With the mechanical impact of fishing gear being dragged across the sea bottom, we have seen the dreadful alteration of eco-system structure and habitat degradation. By-catch is not simply other fish. It includes the death of 40,000 albatrosses a year from long-line baited hooks in the Southern ocean, on lines that stretch for an almost unbelievable 150 kilometres. By-catch also includes the 400,000 dolphins caught and drowned in yellowfin tuna nets. The point is that if we impact on one species, we impact on the whole eco-system. That is why the loss of sand eels around the UK coast has, in turn, been accompanied by a startling decline in arctic terns, kittiwakes, guillemots and puffins. However, it is not just what we take out of the sea that alters those eco-systems. The input into coastal waters of sediment, sewage and nutrients from agriculture and industry has led to widespread eutrophication. Dead zones are now common in the Baltic sea, the Kattegat, the Black sea and the gulf of Mexico. In those areas, it is as though evolution were running in reverse, as higher trophic fish give way to lower trophic species, corals and sea lions die, and jellyfish become the dominant planktivores in a soup of algae and bacteria. The senior researcher at the Scripps institution of oceanography has called the process "the rise of slime". Not only is the loss of biodiversity devastating to the food supply of a global population that is predicted to rise from 6.7 billion to at least 9 billion by 2050, but there is increasing evidence that species diversity is vital for the resilience of marine fisheries. A study in Science by Worm et al in 2006 found that low diversity is clearly connected with low productivity of fisheries and that commercial fisheries face collapse in less than 50 years unless the trends are reversed. The study found that low biodiversity is associated with lower fishery productivity and more frequent collapses of fish stocks. It also found a lower propensity to recover after overfishing than in eco-systems that were naturally rich in biodiversity. Perhaps nowhere is the fragility of our marine eco-systems seen better than in the effects of global warming and rising levels of CO2 in our atmosphere on coral reefs. Some of the carbon dissolves in the upper layers of the ocean, making today's water 30 per cent. more acidic than before the industrial revolution. That acidity affects the pteropods and other forms of life with calcium carbonate shells or skeletons. Coral is particularly at risk from the acidification of the oceans. Coral reefs are some of the oldest and certainly some of the longest-living structures on the planet. One quarter of all sea species spend at least part of their lives in a reef. Globally, 500 million people depend on such reefs for their food and livelihoods. Yet coral bleaching from warmer oceans and increased acidification from higher atmospheric CO2 are putting increased stress on reef ecosystems. Last year, the Global Coral Reef Monitoring Network published a paper entitled "Status of Coral Reefs of the World", in which it was estimated that 19 per cent. of coral reefs were already lost, with a further 15 per cent. under imminent threat and a further 20 per cent. facing loss before 2050. To us in Britain, coral reefs sound distinctly tropical and remote, but cold water coral is particularly at risk from acidification, because colder seas tend to be more acidic anyway. Only 11 years ago, here in the UK, we saw the destruction of part of the Darwin mounds, the extensive colonies of cold water coral off the north-west coast of Scotland, almost as soon as they were discovered. The reason for that ecological vandalism was that trawlermen were eager to get at the large bounty of fish that gravitated to the reef. A bulldozer with an aqualung could not have done a better job of destroying it. I have tried to set out clearly the very real need upon which this Bill is predicated. In that the Bill aims to initiate flexible, integrated coastal zone management in UK waters, including inshore areas and the exclusive economic zone, it is the first serious attempt to set out in statute a framework for marine planning and licensing and a coherent network of marine protected areas that can help to manage our marine environment. Much of this task is being placed under the authority of the new marine management organisation, and offshore fisheries are managed generally under the auspices of the EU common fisheries policy. It is worthy of note—and, of course, welcome—that the Commission is currently reviewing the CFP. I urge the Secretary of State to ensure that the timing of the Bill is propitious in ensuring a seamless integration with a revised CFP. I want to turn briefly to some of the elements of the Bill that have been mentioned so far, and particularly to the need to take into account socio-economic factors. Section 4.2 of the European Commission's green paper makes an important point, which the Bill as it stands does not yet fully take into account. It states:""Economic and social sustainability require productive fish stocks and healthy marine ecosystems. The economic and social viability of fisheries can only result from restoring the productivity of fish stocks. There is, therefore, no conflict between ecological, economic and social objectives in the long term. However, these objectives can and do clash in the short term, especially when fishing opportunities have to be temporarily reduced in order to rebuild overexploited stocks. Social objectives such as employment have often been invoked to advocate more generous short-term fishing opportunities: the result has always been to further jeopardise the state of the stocks and the future of the fishermen who make a living out of them."" I believe that Ministers would do well to heed that advice and to integrate it into the body of the Bill. The prioritisation of short-term socio-economic considerations has led to the setting of quotas for European fish stocks 48 per cent. above scientific recommendations, resulting in chronic overfishing in the European area. Earlier, the Secretary of State referred to the need to take sound scientific advice, and I absolutely agree with him on that. Tragically, however, history shows that politicians have always been keen to ignore that scientific advice when socio-economic and political considerations have come into play. The other issue is that of quantity versus quality, and the question of whether we should designate a proportion of the sea for marine conservation zones. There is now considerable scientific literature discussing the area of marine habitats that need to be protected to ensure the viability of the protected habitats and to contribute substantially to fisheries management. Reviews of that literature by Balmford et al in 2004 suggest that a target to sustain fisheries outside marine protected areas is in the region of between 10 and 50 per cent. of the area of the world's oceans, with a modal value of approximately 30 per cent. In addition, the World Parks Congress has explicitly called for marine reserves to cover 20 to 30 per cent. of all marine habitats by 2012. It is important to look at the science in this context, because this is not simply a question of quality; quantity affects quality, and that factor, too, must be integrated into the Bill. I agree with what hon. Members have already said about the issue of disturbance. In relation to the defence, it is ridiculous that an act carried out for the purpose or in the course of—
